Design problem solving is a complex activity involving a number of subtasks and a number of alternative methods potentially available for each subtask. The structure of tasks has been a key concern of recent research in task-oriented methodologies for knowledge-based systems (Chandrasekaran 1986; Clancey 1985; Steels 1990; McDermott 1988). One way to conduct a task analysis is to develop a task...

This paper presents the implementation of a didactic unit based on Singer's proposal for data-driven learning (DDL) within task-based (TB) framework in context Chilean translation education. The intervention has four stages: 1) data collection from students' preferred multimodal consumption order to generate written corpus transcription popular online TV series, 2) design that graduates concord...

In this paper, an integrated framework for knowledge audit and capture using the task analysis approach is presented. We first identify the types of knowledge that could be ascribed to tasks and analyze a task by breaking it down into subtasks and task elements. We then identify the skills and knowledge required to perform the tasks at this level. The framework is validated and tested on an exp...

T here is great excitement in the tuberculosis (TB) scientific community over the introduction of new tools into TB control activities. The development of new tools is an important component of the Global Plan to Stop TB and the World Health Organization's new global Stop TB Strategy [1,2]. Anticipating the introduction of new tools, the Stop TB Partnership has established a Retooling Task Forc...

Chest radiography (CXR) has been used as an effective tool for screening tuberculosis (TB). Because of the lack of radiological expertise in resource-constrained regions, automatic analysis of CXR is appealing as a “first reader”. In addition to screening the CXR for disease, it is critical to highlight locations of the disease in abnormal CXRs. In this paper, we focus on the task of locating T...

this study was planned to determine hiv seroprevalence among pulmonary tuberculosis patients, to characterize the isolated mycobacteria into typical and atypical strains and to evaluate the drug resistant pattern of mycobacterial isolates. the study aims to correlate multidrug resistance (mdr) and hiv seropositivity status in pulmonary tuberculosis patients. during the year 1994-1997, 750 pulmo...
